Thanks a lot for you work:)
I added a small line of code before line 14 of GotoScene.cs which checks if you saved the scene before switching, preventing loss of work:

// check if scene has been modified
if(EditorSceneManager.GetActiveScene().isDirty)
{
	// ask user if he wants to save scene, abort switch if cancel
	if(!EditorSceneManager.SaveCurrentModifiedScenesIfUserWantsTo())
		return;
}

Would be neat if you could add it to the gist :)
